要使用纯PHP创建或编辑Excel电子表格，我们将使用PHPExcel库，它可以读写许多电子表格格式，包括xls，xlsx，ods和csv。在我们继续之前，仔细检查您的服务器上是否有PHP 5.2或更高版本以及安装了以下PHP扩展：php_zip，php_xml和php_gd2。

创建电子表格

创建电子表格是PHP应用程序中最常见的用例之一，用于将数据导出到Excel电子表格。查看以下代码，了解如何使用PHPExcel创建示例Excel电子表格：

// Include PHPExcel library and create its objectrequire("PHPExcel.php");$phpExcel = new PHPExcel;// Set default font to Arial$phpExcel->getDefaultStyle()->getFont()->setName("Arial");// Set default font size to 12$phpExcel->getDefaultStyle()->getFont()->setSize(12);// Set spreadsheet properties – title, creator and description$phpExcel ->getProperties()->setTitle("Product list");$phpExcel ->getProperties()->setCreator("Voja Janjic");$phpExcel ->getProperties()->setDescription("PHP Excel spreadsheet testing.");// Create the PHPExcel spreadsheet writer object// We will create xlsx file (Excel 2007 and above)$writer = PHPExcel_IOFactory::createWriter($phpExcel, "Excel2007");// When creating the writer object, the first sheet is also created// We will get the already created sheet$sheet = $phpExcel ->getActiveSheet();// Set sheet title$sheet->setTitle("My product list");// Create spreadsheet header$sheet ->getCell("A1")->setValue("Product");$sheet ->getCell("B1")->setValue("Quanity");$sheet ->getCell("C1")->setValue("Price");// Make the header text bold and larger$sheet->getStyle("A1:D1")->getFont()->setBold(true)->setSize(14);// Insert product data// Autosize the columns$sheet->getColumnDimension("A")->setAutoSize(true);$sheet->getColumnDimension("B")->setAutoSize(true);$sheet->getColumnDimension("C")->setAutoSize(true);// Save the spreadsheet$writer->save("products.xlsx");

如果要下载电子表格而不是将其保存到服务器，请执行以下操作：

header("Content-Type: application/vnd.ms-excel");header("Content-Disposition: attachment;filename="file.xlsx"");header("Cache-Control: max-age=0");$writer->save("php://output");

编辑现有电子表格

在PHP中编辑电子表格与创建电子表格类似：

// Include PHPExcel library and create its objectrequire("PHPExcel.php");// Load an existing spreadsheet$phpExcel = PHPExcel_IOFactory::load("products.xlsx");// Get the first sheet$sheet = $phpExcel ->getActiveSheet();// Remove 2 rows starting from the row 2$sheet ->removeRow(2,2);// Insert one new row before row 2$sheet->insertNewRowBefore(2, 1);// Create the PHPExcel spreadsheet writer object// We will create xlsx file (Excel 2007 and above)$writer = PHPExcel_IOFactory::createWriter($phpExcel, "Excel2007");// Save the spreadsheet$writer->save("products.xlsx");

准备电子表格进行打印

要准备电子表格进行打印，我们将设置纸张方向，尺寸和边距：

$sheet->getPageSetup()->setOrientation(PHPExcel_Worksheet_PageSetup::ORIENTATION_LANDSCAPE);$sheet -> getPageSetup()->setPaperSize(PHPExcel_Worksheet_PageSetup::PAPERSIZE_A4); $sheet->getPageMargins()->setTop(1);$sheet ->getPageMargins()->setRight(0.75);$sheet ->getPageMargins()->setLeft(0.75);$sheet ->getPageMargins()->setBottom(1);

将PHPExcel与Laravel一起使用

PHPExcel库也可以在Laravel框架中使用。查看以下PHP包（此处）并通过Composer安装它。完成安装步骤后，您可以使用以下代码将数据从数据库导出到Excel电子表格中：

Excel::create("Products", function($excel) {        // Set the title        $excel->setTitle("Product list");          // Set the creator        $excel->setCreator("Voja Janjic");          // Set description        $excel->setDescription("PHP Excel spreadsheet testing");          $excel->sheet("Products", function($sheet) {                   // Get data from the database                $products = Product::all();                   // Generate header row                $sheet->row(1, array(                        "ID",                        "Product",                        "Price",                        "Quantity",                     ));                  // Generate data rows                 $i = 2;                 foreach($products as $product) {                            $sheet->row($i, array(                                   $product->product_id,                                   $product->product_name,                                   $product->price,                                   $variety->quantity,                            ));                           $i++;                }        });})->export("xlsx");
